Every game has little events that keep running long after they're no longer hugely pertinent. Every gamer has anniversaries or dates they remember, or holidays that they feel are important even if the game doesn't have a holiday event. So what small holidays or events do you observe in your favorite games? Do you make a point of memorizing important in-game lore dates and celebrating their anniversaries? Do you take part in no-longer-vital elements, such as the Elemental Invasions in World of Warcraft? Or do you just take the opportunity on days like today to outfit your Star Trek Online crew in green uniforms and hang around drunk?
